Why are these videos so much better than the college courses I pay thousands for
Cause he is enjoying sharing this. They are just making a paycheck....mostly
Because some colleges and universities are scam. Lol.
@Yunki Arcee college will be a breeze for you. Im in my 3rd year of college just learning about this. consider yourself lucky to see it early
@Yunki Arcee same
You guys learning this in college and high school?
Im in 8th grade and having to learn this :) .
Imagine learning more in one 10 minute video than in a whole 3 hour lecture
A 3 hour lecture is crazy
been with this guy since the 10th grade, going into my 3rd year of my biological science degree with a concentration in genetics and evolution...and i'm still here lmao
I have a test in 2 hours and I've been confused about how to tell when a hydrogen bond exists or not. This man solved it in 5 minutes wth props to you mate.
Your videos are awesome. Thanks for always breaking it down in a way that is easy to understand!
This legit explained better than my teacher's 1 hour lecture
Fall semester just started yesterday and I was already struggling with understanding this topic when my professor taught this. He moved too fast, didn't stick around to explain further, and I left lecture so confused. But you just made it so easy! You simplified everything and I am so grateful and happy! Thank you so much!!!!!
So glad I found these. I am returning to school and struggling. I understand this way quicker than reading anything my professor has made up. Amazing. 100/100
Fantastic video. Amazing how I understood this in 10 min
Here to night before my final exam trying to remember intermolecular forces cause they were taught 7 weeks ago….. Always thankful to stumble across your videos
Your videos are awesome.Thanks Chem Saint
literally will hug this man
These videos are so much more helpful than class notes. Thank you so much
Hey..SO2 or NH3 has higher boiling point?
@@gjjnn8793 NH3 has higher boiling point than SO2 because NH3 has hydrogen bonds and SO2 has dipole dipole interactions.
@@CK-nm7chate but those are one of the tricky ones where you have to remember the rules. SO2 will have the higher boiling point because it weighs more. Be on the lookout for that whenever you see Sulfur in a problem.
Hi guys, just want to share my little trick about “boiling point & intermolecular forces”--⬆️higher the boiling point, ⬆️longer the intermolecular force’s name
Lol! That's a great way to remember it
is that true? wouldn't ion-ion be the strongest type of intermolecular force with the highest boiling point and it has the shortest name? ("ion-ion")
And the weakest intermolecular forces would be momentary-dipole induced dipole interactions which has the longest name?? Lol.
Or do you mean, the higher the chemical formula name?
Saboor Chaudry Hi, ionic, covalent and metallic forces are INTRA-molecule forces
yo
mate intramolecular forces and intermolecular forces are different
intramolecular forces is ionic metalic and covalant bonds while intermolecular forces are in this vid
This is so helpful thanks!
I appreciate this mans so much
Wish you were my teacher. you're just so amazing
That was very useful. Thanks!!
We are grateful for efforts, really awesome.
you're amazing
Bro u saved all my grades thank you so much
Thanks! This was very helpful.
Thank you!
Can my teachers learn with u?
lool
hello naegi
This made so much sense oh my god
Great outro!!! Love the vid
this is great....thank you
Thanks to this video just got full marks!
@shinchan sweetie this is barely high school stuff
@@hemeleh8683 found the person who failed chem^^^
@@insanearcane9960 i dont remember what happened but whoever i replied to deleted their comment.
what are u talking abt😟
This is helpful. Thanks a lot
amazing
Good stuff. 👍
THANK U SO MUCH!!!!!
Youre the best
Thanks sir
it is awesome
life saver forreal thanku
My teacher took 45 minutes to explain this and still did a horrible job and continued explaining what he missed the next class. We then moved on to the next part of the unit and now I have a test tomorrow and we barely did anything with this.
Thanks
Thank you
bless ur soul
Awesome
If this helps me pass my test I'll subscribe
do you always have to draw out the structure to find out the imf or is there an easier way to figure it out
I LOVE U OMG 😭
so basically Atoms also cheat on each other
wait how....?
@@deepashasharma9264 atoms aren't loyal to their partners
Thanku
Life saviour..
Which is more soluble in water nh4+ or na + ???
Would you put 1-octanol since the OH would automatically be on the 1st carbon??
my teacher explained this so badly bro and i had a test in an hour ur clutch
Lil update got an A cuz of this video
On a polar and non polar videos
You said that molecules with C And H bonding are non polar but here I heard you saying that ethanol and diamethoetha... are polar
so h-bond make the molecules more polar so they're able to dissolve in water?
wait i have a question is it all non polar have high boiling points??
Non-polar molecules are going to have low boiling/ melting points because they are held together by London Dispersion Forces which happens to be the weakest of all the Intermolecular forces. In other words, they are weak so they are easier to break apart, hence, the low boiling/melting point. If you are comparing two different non-polar molecules W/ (London dispersion forces) then, the one that is less compact/has more contact surface area will have a higher boiling point.
1:50 I don't understand this. Carbon has only 4 valence electrons. 3 are tied up in the triple bond with oxygen. How can it have 2 electrons left over?
I think it has to do with the octet rule and filling 8 electrons. The bonds take up 6 and there are 2 left over. If someone else could verify also to make sure.
Why does the carbon monoxide molecule has a triple bond as opposed to a double bond? Because Oxygen can only form two bonds not three.
Oxygen prefers to have double bonds, but it could occasionally have triple bonds, resulting in oxygen being positively charged. Considering that carbon could have four bonds, that makes the rare possibility of oxygen having a triple bond greater. Hope this helps!
Hi, please how do you make your videos. I really think its cool. I would love to make this sort of videos in the future. Will you tell me how?
Hi sir why did u say CH3Ch3oH
Hidrogen bond
U said that hydrogen bond only between two molecules
There are hydrogen bonds within the molecule's covalent bonds. This means that these molecules have the potential to interact with other molecules through hydrogen bonding.
Solubility is not due to Hydrogen bond, but it is due to the molecule being "Polar".
Polar desolves in Polar.
He said that
H bond makes a compound polar.
a good way to remember this is “like dissolves like”
I dont get how in the first few minutes when he was explaining dipole dipole, how do you know if an atom has a partial charge or not? and how do you know if its positive?
the symbols he used are called sigma. a positive sigma represents the least electronegative element, and the negative sigma represents the most electronegative in the elements’ bond. The dipole arrow will point towards the most electronegative element in the molecule. Dipole-dipole moments are usually occur in a polar molecule.
Therefore, a dipole-dipole is just when you combine two polar molecules.
@@jamesp.406 Thanks! :D
please tell me this helps.
shit is hard af
in this video..
I'm gonna talk about
how does he know if there is a partial charge there or not
I believe it has to do with the electronegativity. The dipole moment arrow will always point towards the more electronegative atom.
how does CH3 have hydrogen bonds?
CH3OH. That Hydroxyl group (OH) on the end will form hydrogen bonds with other CH3OH molecules.
Teachers need public speaking training with animation gesticulation techniques to hold student attention to colorless subject matters and flat out boring lectures. .
In carbon triple bond oxygen here in resonance structure c atom negatively charged & o atom positively charged... But why u said that c atom has partial positive & o atom has partial negative charge????
You're thinking about formal charges. He's talking about polarity. O is more electronegative than C
Formal charges are different than electronegativity
Idk carbon sus
"OH" is not a Hydrogen bond! although there is a covalence bond between hydrogen and Oxygen, it is not categorized as Hydrogen bond. Hydrogen Bond is intermolecular bond, and easily break (compare to Covalence bond in OH).
A bond between oxygen and hydrogen actually is a hydrogen bond. Just reviewed it in AP Chem this week :)
@@ariahite3912 Hi Aria,
Could you provide a quote, please? Very hard to believe. I've ALWAYS seen it described as a polar covalent bond.
@@ariahite3912 In the vid I've linked to, Tyler specifically sz the OH bond CANNOT be a hydrogen bond: th-cam.com/video/PyC5r2mB4d4/w-d-xo.html
how does oxygen have 8 partially negative charged? @ 0:41
thats the symbol for delta, not the numerical digit "8". Delta negative means it has a negative charge due to the electrons spending its time closer to the oxygen, as the oxygen is more electronegative than carbon
Thank you! I realized that shortly after I said that
@@bobbymcdermott5013 no worries 👍
POV: you have a test today
ty bro again as always
